Once you have understood the importance of achieving and optimal stroke length, and have seen what estimated range of SPL (strokes per length, or stroke count) you should aim for, you are ready to get to work on it. It becomes a very clear, concrete, measurable goal to work toward.
But there are a couple ways you could go about this.
You could get very focused on this one development goal and devote most of your practices to it for weeks or months to gradually get it into your optimal range. That might fit the personalities of some people.
If your current stroke count is far from the edge of your estimated optimal zone, like more than 5 strokes (for a 25m pool), then you might consider taking a step-by-step approach.
There are these three stroke length training objectives you will train for:
- reach optimal stroke length
- hold consistent stroke length over distance
- increase the distance over which you can swim with consistent stroke length
For example, Nilda has a current SPL of 27. The edge of her Green Zone (optimal SPL range) is 20. Instead of parking it on Objective #1 and working and working to get her SPL from 27 to 20 in one long effort, she might set an initial goal of lowering your SPL to 25, then using that SPL 25 and work through Objective #2 and then Objective #2. Then come back to Objective #1 again, and make a new goal of lowering your SPL by another -2 to SPL 23.
She can work through this cycle several times so that she is building building fitness and technical control in a more proportional way.
